ssa_speed script in cron

I'm getting cron job failed message in cron log for this cron job on all my AIX boxes.

30 4 * * * /usr/lpp/diagnostics/bin/run_ssa_link_speed 1>/dev/null 2>/dev/null

No further information about failure. and when I tried to manually run it, it looks like no error.

Anyone know about it? I'm a Solaris admin and junior on AIX.

BTW, the OS version is 5300-08-03-0831

Thanks

This is normal if you do not have any ssa adapters.

lsdev -Cc adapter | grep -i ssa

no output means you have no ssa adapters and the following lines can be commented out of, or removed from, the cron table:

01 5 * * * /usr/lpp/diagnostics/bin/run_ssa_ela 1>/dev/null 2>/dev/null
0 * * * * /usr/lpp/diagnostics/bin/run_ssa_healthcheck 1>/dev/null 2>/dev/null
30 * * * * /usr/lpp/diagnostics/bin/run_ssa_encl_healthcheck 1>/dev/null 2>/dev/null
30 4 * * * /usr/lpp/diagnostics/bin/run_ssa_link_speed 1>/dev/null 2>/dev/null

That's exactly the case. I was thinking the script was not applicable on my box. Just not sure how to confirm if there is any SSA device.

Thanks a lot.
